Sounds like a bad fuel pressure regulator,this located on the fuel rail that the injectors are on it has a vacum hose going to it,a small one,if you remove this vacum hose and there is fuel on the hose side this is bad even just a small amount,there should be no liquid on the vacum hose side,becarefull when replacing,you must relieve all fuel pressure 1st

hello, it sounds like the ECT (engine coolant temperature sensor) is failing, the sensor communicates with your computer and has affect on fuel usage, it is common for bad sensor to allow too much fuel and cause cylinder flooding, this in turn will lower cylinder compression and cause miss, black smoke, check engine lights, easy too overlook without propper diagnostic equipment, easy too change and fairly cheap! good luck, marty

Grand am smells like gas inside the car


I would definatly recheck the regulator to make certain you do not have any leaks.
But to be clear, you are smelling gas and not exhaust?
Also, is you cowl seal in good shape, not missing or damaged in any way?
Let me know.

Fuel?


It may be due to a failed/faulty fuel pressure regulator. I had this problem: easy start when cold, hard starting when warm/hot, and rotten egg smell from exhaust when warm/hot. My mechanic diagnosed a failed/faulty fuel pressure regulator, replaced it, and now the problems (warm hard start, smell) are gone. I have a '92 GT with L4 engine.

I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.

Could have a bad map sensor. The Map sensor is located on the throttle body. I have seen countless Jepp that start blowing black smoke when they go bad. That would be a good starting place.
